Max Payne 3

HI,I have purchased max payne 3 yesterday, downloaded. when i tick "play" it brings an error of "failed to contact key" or something. internet is working.trying to load the game from it's own folder fails as well.I have submitted a complaint in support but no response. Couldn't find a phone number to call them.Any advise?

1.Make a text document2.Name it "steam_appid.txt" (without quotes)3.Inside the text doc type "204100" (no quotes again) save and add it to the your Max Payne 3 directory4.Dont start the game from steam,but from the game directory.5.When ingame press your steam overlay key.Now you should be able to see the cdkey.
